  • Does this method survive a reboot? Commented Jul 2, 2017 at 16:50
  • Yes it does survive a reboot since I have tested it myself. I searched google play and found no apps that could do this. I will make an app myself using this method and upload it to the play store so others like me can have an easy way to change the resolution. Thanks @SSS Commented Jul 2, 2017 at 20:03
  • This really does help, usually I lose around 30%/day normal use but I'm barely losing 20%/day nowadays. For anyone else doing this on s4, the best dpi for 720x1280 in my opinion is 300. I had 480 when resolution was 1080x1920 Commented Jul 3, 2017 at 21:33
